Background Radiation therapy is the treatment of pelvic cancers, with diarrhea often being the most frequent acute side effect. This study aimed to determine the efficacy of partially hydrolyzed guar gum (PHGG) usage in reducing radiotherapy‐induced diarrhea and improving bacterial count, nutrition status, and quality of life (QoL) among cancer patients. Methods Adult patients undergoing pelvic radiation were recruited and randomly assigned to receive supplementation of either 10 g of PHGG or placebo (maltodextrin) twice daily, 14 days prior and 14 days during pelvic radiation. Diarrhea frequency, fecal samples, nutrition status, and QoL were assessed at baseline and days 14, 28 (2 weeks after pelvic radiation), and 45 (at the completion of pelvic radiation, 2 weeks’ postsupplementation). Results A total of 30 patients (mean age 56.5 ± 10.8 years, 75% malnourished) participated. The mean of diarrhea frequency in the intervention group (IG) was higher compared with the control group (CG) from days 14 and 28 but reduced at day 45. There was a significant intervention effect after controlling for confounders (ie, baseline diarrhea, age, nutrition status) (P < .05). Bifidobacterium count increased by double among the IG at 14 days of PHGG supplementation, whereas such trend was not observed in the CG. Conclusion Supplementation of PHGG potentially increased the bifidobacterial count and seemed to have post‐supplementation effects by reducing the frequency of diarrhea upon the completion of pelvic radiation treatment.
Working memory is developed in one region of the brain called the dorsolateral prefrontal cortex (DLPFC). The dysfunction of this region leads to synaptic neuroplasticity impairment. It has been reported that several biochemical parameters and anthropometric measurements play a vital role in cognition and brain health. This study aimed to investigate the relationships between cognitive function, serum biochemical profile, and anthropometric measurements using DLPFC activation. A cross-sectional study was conducted among 35 older adults (≥60 years) who experienced mild cognitive impairment (MCI). For this purpose, we distributed a comprehensive interview-based questionnaire for collecting sociodemographic information from the participants and conducting cognitive tests. Anthropometric values were measured, and fasting blood specimens were collected. We investigated their brain activation using the task-based functional MRI (fMRI; N-back), specifically in the DLPFC region. Positive relationships were observed between brain-derived neurotrophic factor (BDNF) (β = 0.494, p < 0.01) and Mini-Mental State Examination (MMSE) (β = 0.698, p < 0.01); however, negative relationships were observed between serum triglyceride (β = −0.402, p < 0.05) and serum malondialdehyde (MDA) (β = −0.326, p < 0.05) with right DLPFC activation (R2 = 0.512) while the participants performed 1-back task after adjustments for age, gender, and years of education. In conclusion, higher serum triglycerides, higher oxidative stress, and lower neurotrophic factor were associated with lower right DLPFC activation among older adults with MCI. A further investigation needs to be carried out to understand the causal-effect mechanisms of the significant parameters and the DLPFC activation so that better intervention strategies can be developed for reducing the risk of irreversible neurodegenerative diseases among older adults with MCI.
Stress is a common problem among university students and studies showed that involvement in exercise could help in reducing stress. However, information regarding the effect of high intensity progressive resistance training (PRT) using a resistant tube on stress among inactive and moderate active young male university students is limited. Hence, the aim of this study is to examine the effect of high intensity PRT (n = 14, umur: 21.50 ± 1.37) mengikuti PRT intensiti tinggi dengan menggunakan tiub rintangan 3 kali seminggu selama 10 minggu; kumpulan kawalan (n = 16, umur: 21.29 ± 1.86)
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
